The shaft 25 'carries-also a pulley 2G over-which runs a belt 27 toa double pulley 2S .carried by one of the joints l5. A belt 29 runs from the last mentioned pulley to a pulley 30 arranged upon the outer end portion ofthe shaft 18.

To prevent the. cotton winding about the drum 20 and insure Vits delivery-into'the tube vI preferably arrange rollers 3l and 32 -in the lower` portion of the mouth and-'a belt 33 travels over said rollers and in close proximity to the Wire drum 20. This vbelt will draw the cotton from said drum and start it inwardly through the collector. -It is of course understood thatthe suctionfan- 1s ,drawing a strong current of air through;

f the collector and tube, said current passing through the drum 20. Thisl airv suction' 'draws the cotton to the drum which 'immediately whirls it i'nto the collector and lipon the belt 33, and the air current carries it on to the suction chamber 10, wherethe cotton is deposited onl the screen 12. The roller 32 carries upon .the exterior of, the collector a pulley 33a' which is also driven bythe belt 29. l

' VVhileI have shown the rollers-3l and 32 and belt 33 as arranged for the/purpose of preventing any winding'of vt-he cotton 'about the drum, these parts are not considered absolutely essential as with'a strong currentv 5 of,- air there would be little danger of any' cotton sticking to the drum after it had passed to the rear side of it, that' is within the collector. This belt 33 therefore is in cluded Vsiinplyas a precautionary measure,

it may be discarded lwithout appreciablyl affecting the operat-ion of the device.

From'the fan casing there lextends downwardly an air discharge tube 35 which adjacent its lower end communicates with the lower end of the suction chamber 10. This tube therefore forms adischarge for both thle) cotton and the air from the collecting tu e. 4

In order to support the device suitable bars 36 are employed, and an overhead frame 37 is secured at its rear end to the upright frame 2 and at its forward end ble paddles 4l, spaced apart so as not to interfere with the passage of air to the screen, but at the same .time arranged sufciently said shaft close together that they will wipe from the screen all cotton that might otherwise tend .tostick tothe screen. These shown are arranged in longitu inal rows along lthe drum' and positively force the cotton into the lower portion of the tube 10.`

'In this lower portion is arranged a second drum .42, provided with longitudinally ex vltending blades 43,' which extend entirely 'across .thejtube 10 and feed the cotton from said tube into the dischargev tube 35 and at thesame time these' blades act as valves pretube .35 outwardly into the tube 10. By means of'thisarrangement a very quick vand effective discharge ofcotton is provided for 'without-any danger of clogging the tube 10 addles as(l vventing ingress of air from the discharge either by the fcotton' collecting upon the screen 12 or by reason of an upward current fof air .in said'tube which will of course tend to' retard downward movement of the cot ton. The drum 42 'is driven by-,thefbelt 21 and Aa belt 44 from said' drum 42 drives the drum? 40, as` 4shown most clearly F ig. 7.

1. In a cotton picker, 'aA iexible tube, means for-creating currentl of air therethrough, a collector, said collector being cylindrical at itsinner" end and rectangular at its outer end, the cylindrical end being rotatably mounted in said flexible tube, and

a rotatable reticulated drum arranged in the outer end lof said collector, the air current passing into said collector through said drum.-

- 2. In a cotton picker comprisinga leiible tube, means for creating an air suction :in

said tube, a collector rotatably mounted -upon the end of thetube, a rotatable reticulated drum carried in the outer end of the collect-or, rollers transversely 'journaled in vsaid collector and adjacentsaid drum and a .belt 'running over said rollers.

3. A collector for cotton pickers consisting of a casing cylindrical at its rear end andl enlarged and rectangular at lts'front end, the front end being cut away upon itsl under side, and said cut-away portion being I' closed at'the end, a rotatable I eticulated drum mounted in the upper portion of the collector, and projecting in advance .of the closed end portion, and an endless belt ar ranged in the lower portion and adjacent said drum, said belt-'beingadapted to travel longitudinally with respect to the collector,

as and for the purposeset forth.
